I’m not sure how this happened. I didn’t set out to write a weekly column. It wasn’t part of my “plan”. It started last summer as a request to put a few paragraphs together on media and marketing. But no one shouted stop. Last week, to my genuine amazement, I filed column number 23. As that 17th-century “columnist” John Milton might have put it, 23 seemed an auspicious number and a good time for a little reflection before “my hasting days fly on with full career”.
